    ABSTRACT »

    This thesis is a study of the decoherence mechanisms effecting the apparatus. A feed forward magnetic field stabilisation is presented, aiming at the reduction of magnetic field noise. Furthermore, the dephasing due to magnetic field noise is classified as homogeneous, by carrying out homogeneous dephasing insensitive Ramsey interferometry. During the process of this thesis an analysis technique was developed to investigate the dephasing due to transition frequency fluctuations of the implemented qubit on the example of magnetic field noise. Revealing a full understanding and prediction of the coherence due to the investigated noise source. As an outlook for further investigations a post correction for magnetic field noise effecting the apparatus is presented, indicating a limit for future magnetic field stabilisations.
